.sheet no longer dismissable in WatchOS 7?

Code Block 
navigiationTitle{
	button("Done"){
		//Dismis the .sheet 
	}
}

Seems to continue in watchOS 8. I have filed feedback about this with the release of watchOS 7 already. (FB9055341)

EDIT: On Stackoverflow I found out that this issue is actually due to a SwiftUI change. The title of a sheet on watchOS is no longer an actual title, but a button in a toolbar. To change it you can overwrite the toolbar:

MySheet().toolbar {

                ToolbarItem(placement: .cancellationAction) {

                    Button(title, action: action)

                }

            }

In the action you can use the environment value for presentationMode to close the sheet.

The button will be clickable and it will replace the cancel title. So this is more a documentation and restructuring issue that almost no one caught.

The fix is actually much simpler (at least for me running watchOS 10). If you embed your sheet view in a navigation stack like this, there will be a little circular "X" button at the top left of your sheet.

MyMainView()
  .sheet {
    NavigationStack {
      MySheetView()
    }
  }

As it turns out, the default cancel button is embedded in the toolbar, and the toolbar doesn't show up at all unless your view is embedded in a navigation stack
